This is an Art Deco diamond solitaire ring from the 1920s, fashioned from platinum with a silver and clear colour palette. The piece centres on a 1.25 carat old European cut diamond that sits 8.0mm from the finger, held within a mounting that displays detailed open foliate decoration, fine milgrained edges, and engraved scroll shoulder detailing along the shank. The photograph reveals a round diamond with complex facet patterns, open-work filigree metalwork featuring delicate scroll and leaf motifs, and finely engraved linear patterns along the side of the band. This ring suits formal wear or everyday accessorising as a distinctive fine jewellery piece. It slips easily onto the hand to be worn on a finger for social events, celebrations, or daily use.

FAQs

Art Deco engagement rings, produced predominantly during the 1920s and 1930s, are characterised by geometric forms, delicate filigree work, and hand-engraved details, often crafted in platinum or white gold.

Rings from this era were primarily constructed using platinum or 18ct white gold to achieve a bright silver appearance, paired with hand-cut stones such as old European cut or mine cut diamonds.

An authentic old European cut diamond features a small table facet, a high crown, a deep pavilion, and a visible open culet at the base, resulting in a distinct light reflection pattern compared to modern brilliant cuts.

An antique solitaire ring can be styled alongside a slim modern wedding band or mixed with plain metal stacking rings to highlight the intricate filigree and central gemstone of the vintage piece.

Clean vintage filigree rings using warm water, mild soap, and a soft-bristled brush to gently remove debris from fine pierced details without disturbing delicate settings.
